STRAW STAGKER.

Application filed August 15, 1921. Serial No. 492,622.

To all whom it may concern:

Be it known that I, JOHN B. MASERANG, a citizen of the United States, residing at Belleville, in the county of St. Clair, State 5 of Illinois, have invented certain new an .iseful Improvements in Straw Stackers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to. which it appertains to make and use the same.

The object of the invention is to provide a pneumatic straw stacker whereby the formation of the stack and the deposit of the straw or any equivalent material in the formation thereof may be facilitated with the minimum expenditure of efiort on the part of the operator and insuring a stable formation under conditions conducive to the effective drying and curing of the straw; and more especially to provide in connection with the blower pipe constituting or in communication with the outlet from the thrashing machine a hood or deflector supported by and movable with relation to the blower pipe to determine the distribution of the straw as it leaves the outlet of the blower pipe, and to prevent the scattering of the same even in the event of counterwinds 01' atmospheric disturbances adjacentto the'location of the stack; and with these general; objects in view, supplemented by more specificobjects which will appear in the course of the following description, the invention consists in a construction, combination and relation of parts of which a preferred embodiment is shown in the accompanying drawings, wherein: 1

posed, for example in a downwardlyinclined position and arranged directly in front of showing the arrangement of the crosshead, the roller and the stirrup. I

Figure 9 is a detail view, in perspective, of the clip carried by the drumwhereby the The blower pipe '10 may be of any ordinary, well known or preferred construction designed as a means of conveying the straw or other material to be stacked by means of a blast of air from the thrashing machine or other source (not shown), the same preferably having a more or less extended straight portion 10 constituting What for convenience may be termedan outlet nozzle disthe outlet nozzle and adjacent thereto, and therefore in the path of the blast of air and material discharged therefrom, is a hood or deflector 11 of cross sectional trough shape with the upper end thereof returned or extended rearwardly to form a cap 12,-open at its under side and closed at the end to provide for catching and redirecting material into the path of the blast if carried upward by eddies formed by the impactof the'b-las't against the surface of the hood. The hood or deflector is preferablyof a width considerably in excess of that ofthe outlet of the blower pipe with its lateral flangesdisposed to prevent transverse scattering of the straw or other material, and the lower section 13 thereof is preferably hinged asat 14 for forward swinging movement and is yieldingly held in'alignment with the upper section of the hood or deflector by contractile springs 15 which, however, are extensible to'permit of the swinging movement'of the lower section when strain is applied to an operating rope 16 terminally attached as at 18 to the main section at the front 'or outer side'of the hood, and extending downwardlyland around a direction pulley 17 on the lower section, said cord further extending upwardly and over a direction pulley 19 at'the I upper end of the hood and through a guide eye 20 supported by the end of the blower pipe, and being'engaged'at its free rear end, within convenient'reach of the operator. of the mechanism, in a fork 21 where it is fitted i with a handheld 22, said cord preferably being provided with stop buttons 23 for selective engagement with the fork to hold the cord and hence the lower section of the hood or deflector at the desired adjustment.

The hood or deflector is carried by the blower pipe through the agency of a slide frame consisting essentially of parallel side bars 24 the forward ends of which are carried by a bracket 25 secured to the pipe, while the rear ends are secured to a band 26 which embraces and is movably mounted upon the blower pipe, said bars being spaced laterally from the blower pipe and connected with the band by means of segmental brackets 27 and being arranged to traverse guide rollers 28 mounted in the brackets 25, as clearly shown in Figure 3. The band 26 carries grooved rollers 29, located respectively above and below the blower pipe to traverse track rails 30, arranged longitudinally of and secured by rivets or otherwise to the blower pipe and serving to facilitate the movement of the slide frame with reference thereto.

Mounted in a suitable frame 31 secured to the blower pipe near its rear or inner end is a spindle 32 having a terminal operating crank 33 and provided with a squared or cross sectional angular body portion 34 up on which is fitted a drum 35 of which one of its terminal flanges 36 is peripherally notched as shown at 37 for engagement by a latch 38 mounted upon the frame 31 and yieldingly held as by gravity in position to engage the notches to secure the drum in its adjusted positions. A hook bolt 39 carried by the spindle engages an opening 40 in the drum head 36 to lock the drum in the proper posit-ion upon the spindle, said hook bolt being provided with a suitable nut 41.

In addition to the drum and its connec tions the means for advancing and retracting the hood or deflector and the slide frame by which it is carried the present device includes a cable 42 crossed and terminally connected with the drum to be reeled thereon in opposite directions, so that when the drum is turned in one direction it will pay out the cable at one side while reeling it at the opposite side, the cable being held spaced apart just forward of its crossing point by a pulley or guide roller 54, the further purpose of which will be more fully hereinafter explained and the loop or bight of the cable engages and extends around a pulley 43 carried by the forward end of the blower pipe, connection between one side or run of the cable with the slide frame being effected by means of a cross head 44 carried by the band 26 said crosshead being cut away to provide parallel guide rods 45 and 46 between which operates a roller 47 mounted in a stirrup; 48, the cable being divided at this point to provide extremities which are attached as indicated at 49 to the ends of the stirrup, so that as the drum is turned in one direction or the other to reel and unreel the sides or runs of the cable, the roller 47 exerts pressure either forward or rearward against the guide rods of the cross head, and thus impels the slide frame either forwardly or rearwardly to extend or retract the slide frame and thus properly position the hood or deflector with relation to the outlet of the blower pipe, such movement of the hood being in the direction of the blast discharged from said pipe to effect the deposit of the straw or other material in the desired position upon the stack.

The terminals of the cable are preferably connected respectively with the heads or flanges of the drum by means of clips 50 having suitable eyes 51 to afford by means of bolts or rivets 52 a suitable pivotal relation therewith, said clips having spaced side walls 53 and 53' for embracing the ends of the cable to minimize the tendency of the related parts of the mechanism to chafe and cause the breakage of the cable. Between the cross head, by which connection is established between the cable and the slide frame, and the drum, there is located a cable positioning means, serving as the cable is actuated by the turning of the drum, to lay the cable thereon in successive adjacent coils without overlapping, and in the construction illustrated said distributing means consists of the peripherally grooved guide pulley 54 arranged in the path of and traversed by the cable so as to receive rotary motion therefrom in opposite directions according to the direct-ion of movement of the cable, said pulley being interiorly threaded and fitted upon a feed screw 55 arranged transversely of the blower pipe or parallel with the cross head and supported by suitable brackets 56 which may as shown extend from the frame 26 which supports the drum. As the cable is fed by the drum the guide pulley receives rotary motion in a corresponding direction and is thereby moved longitudinally of the drum to properly position the cable thereon, while the corresponding movement of the draft pulley 47 carried by the cable serves, regardless of the position of the cable, to transmit motion to the cross head to either extend or retract the slide frame and hence properly position the hood or deflector.

The fact that the guide roller 47 is permitted to slide in. the guide rods. transversely of the frame as the said frame is moved longitudinally of the blower pipe, greatly facilitates the winding and unwinding of the cable on the drum. This construction permits the cable guiding or positioning means to slide freely in order to lay the cable in successive adjacent coils on the drum while, if the guide roller was not slidable transversely, this operation could not be efficiently accomplished.

The pulley is preferably carried in a stirrup 57 to which is connected an adjusting bolt 58 fitted with a nut 59 which is adjustable to take up slack in the cable a2, and the pivot bolt 60 of the pulley preferably extends through a slot 61 in a guide bracket 62 bolted, riveted, or otherwise attached to the blower pipe and serving to render the structure sufficiently rigid to adapt it to resist the strains applied thereto in the adjustment in opposite directions of the hood carrying frame.

WVhat is claimed is:

A straw stacker having a blower pipe, a frame movably mounted on said pipe, a blast directing hood carried by the said frame and means for operating the said frame including a drum, a cable, having its extremi- I ties secured to said drum and adapted to be oppositely reeled thereon, a longitudinally adjustable guide roller carried by the pipe which the loop of the cable traverses, a crosshead supported by the frame, said crosshead being formed with spaced parallel guide rods, and a guide roller interposed in one run of the cable and traversing said guide rods.

In testimony whereof, I aflix mysignature, in the presence of two witnesses.
